My big issue with Beethoven is that he always wrote about himself. All the time. Everything, every note is about himself. I went through a period of avidly listening to Beethoven all the time. It seemed so free after listening to nothing but Mozart for several years, so impetuous and passionate. Then I went through the 19th century as a whole, ending up with Mahler and Strauss and Schoenberg's Gurrelieder, and revisited Mozart with a new appreciation of just what an absolute genius he was. I now prefer Schubert to Beethoven, but still rank things like the Appassionata sonata, the Hammerklavier sonata, the last three sonatas, the last quartets, the Missa Solemnis, the 4th piano concerto, the violin concerto and the Ninth symphony as some of the greatest achievements in Western music. 'Fidelio' I just can't listen to as it bores me to death.
